To aZZ 'whom t may concern:

Be it known that I, JOHN R. BALL, a citizen of the United States, residing at Durango, in the county of La Plata and State of Colorado, have invented certain new and useful. Improvements in Journal-Bearings; and I do declare the following to be a full, clear, and exact `description of the invention, such as will enable `others skilled in the art to which it appertains to make and use the same.

This invention relates to journal bearings, and it relates more particularly to an improved adjustable and self adjusting bearing. i

One object of this invention is to provide an adjustable bearing which is especially useful in connection with the Ball ore pulverizers, which I am engaged in the manufacture of, and which is also useful in connection with similar machines in which a tumbler is mountedto rotate .on inclined tubular journals, and more especially where it is necessary or desirable to vary the inclination of the journals;

Another object is to provide an improved adjustable and self adjusting journal of very simple and practical construction, and to generally improve, simplify and lessen the expense of devices of this kind.

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings in which:

Figure 1 is a vertical sectional view through one of my improved ore pulverizing machines provided with my improved adjustable and self adjusting journal bearings, this view being intended to show only one of the various applications of this im proved journal bearing;

Fig. 2 is a vertical sectional view taken along the line 2-2 of Fig. 4 and showing my improved journal bearing approximately in full side elevation;

Fig. 3 is a vertical sectional view taken along the line 3-3 of Fig. 4; and

Fig. 4 is a vertical sectional view taken along the line 4-4 of Fig. 2.

Referring to these drawings in detail, in which similar* reference characters correspond with similar parts throughout the several views, attention is directed to Fig. 1 for the purpose of pointing out the special adaptability of these improved journal bearstance, these journals are compound, that is, l

they are each composed of an inner member or lining 8 and an outer member 9. However, the part thus far described is a minor part of the'present invention being merely an element of the combination which includes the bearing elements to be presentlyV described.

Referring now to Figs. 2, 3 and 4, my improved adjustable `and self adjusting bearing comprises a sole plate or subbase 10, a bearing 11 and a journal support 12, the latter being provided with a journal seat 1'3 and the oppositely extending journals 14,

the latter having their axes disposed substantially radially with relation to the jour- I nal seat 13. As it is not Vintended for these journals 14 to perform a complete rotation or revolution, but to have a slight rotary movement, `they are made semi-cylindrical, as shown in Fig. 2. Each support 12 is formed with recessed lugs '15 which are adapted to receive bolts 16 for securing a cap 17 over the seat 13 so as to complete Ythe journal box in which the journals 6 and 7 are mounted for rotation (see Fig. 1).

The vertically adjustable bases 11 are each formed with a pair of spaced journal seats 18 in which the journals 14 are seated respectively. Each base 11 is provided with a plurality of adjustable screws or bolts 19 having hemispherical lower ends which are seated in depressions 20 which are formed in the sub-base 10. The sub-base 10 is provided with upwardly extending flanges or guides 21 against which two opposite sides of the base 11 slide in its downward and upward movements. It will be seen l:from the foregoing description that either one of the bases 11 may be adjusted vertically by means of its screw thread members 19, and that when thus adjusted, the supports 12 will be automatically adjusted in accordance with the difference of elevation of the two bearings which support the journals.

This form of bearing is particularly useful and desirable in connection with devices of the character disclosed in Fig. 1,

said journal seats respectively.

because it is desirable to effect a considen able change in the inclination of the axis of rotation, according to the varying circumstances attending the use of such devices.

Although I have described this invention in minute detail, it is to be understood that my invention is not limited to these exact details of construction and arrangement of parts, but that I am entitled to make such minor changes that do not constitute a dearture from the inventive idea set forth 1n the foregoing description.

What I claim for my invention is:

l. In a journal bearing, a base provided with means for raising and lowering it and with a pair of spaced journal seats, and a journal support comprising a journal seat and a pair of journals, the latter extending radially from the last said journal seat in opposite directions and seated in the first 2. In a journal bearing, a base provided 'With means for raising and lowering it and with a pair of spaced journal seats, a subbase supporting said means and provided with means for guiding said base independently of the raising and lowering means, and a journal support comprising a journal seat and a pair of oppositely extending journals radially disposed with relation to this journal seat and seated in the first said journals respectively.

3. The combination of a rotatable member having journals disposed with their axes at an inclination, a plurality of journal suports each comprising a seat for one of the ournals of said member and also compris- 111g a pair of oppositely extending journals disposed radially with relation to said seat, 4e and a plurality of bases each provided with means for raising and lowering it with relation to the other of said bases, each of said bases comprising a pair of spaced journal seats each having one of said oppositely extending journals seated therein.

4. In combination, a rotary member provided with journals, seats in which said journals are rotatable, bases supporting said seats in a manner to allow rotary movement 5o thereof in the plane of the axes of said journals, and means for raising and lowering one of said bases with relation to ythe other of the bases.

5. In combination, a rotary member provided with journals, seats in which said journals are rotatable, bases supporting said seats in a manner to allow rotary movement'- thereof in the plane of the axes of said journals, and means for raising and lowering either of said bases with relation to the j other of the bases. l

6. In combination, a hollow rotary member provided with tubular journals, seats in which said journals are rotatable, bases supporting said seats in a manner to allow rotary movement thereof in the plane of the axes of said journals, and means for raising and lowering one of said bases with relation to the other of the bases.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
